Instead, I'll use the Adafruit I2S stereo decoder to produce a line-out ESP32-LCD-Kit is an HMI (Human Machine Interface) development board based on ESP32-DevKitC (need to purchase if you didn’t have one). io It also has all of the I/O you would expect something based on an ESP32 to have, such as I2S stereo DAC, an I2S microphone input, I2C GPIO extenders and, of course, a built-in MicroSD card reader. Since it’s digital audio, it sounds really good, much better than the raspberry pi This DAC was a cheap and brilliant way to improve the audio quality of my esp32 project.

ESP32 also has 10 touch sensors embedded in it. I have come up with a plan to use a microphone in a Parabolic reflector system, with a mic very similar to this. In this case the sketch is setup for a 32Khz, 16-bit, Mono audio file ESP32 Composite Audio. It is better to use an external DAC with better resolution (12-24 bits) and use the I2S bus of the ESP32.

The NXP UDA1334A is a jack-of-all-I2S-trades: you can use 3. Esp32 audio dac So I reverted to testing it on an Arduino Duemilanove.
